Why does uTorrent keep stopping?

[sake]

I had a problem with 1.8.4 and windows 7 the problem was it would upload really fast and then drop to zero every 30 seconds
and i thought it was my hdd or settings in utorrent and then i just downgraded to 1.8.2 with no problems what so ever and all my torrents and setting remained the same and no more fluctuation in upload speed or any kind of problems.

almost forgot i had the same issues with 1.8.3 speed up and then down 1.8.2 was a winner in my case

Just the same problem buddy. I`ll do the same like you. Thank you
